ATTORNEY 6 of small as well as large dimensions, or can-' Patented Feb. 11 193 0 EINAR ARTHUR. JOHNSON, OF BROOKLYN, NEW YORK 'BULLET AND BULLET GUIDE Application filed September 17, 1927. Serial No. 220,077.

This invention relates to improvements in bullets and bullet-guides, and the principles and ideas embodied herein are equally applicable to the projectiles-emanating from guns nons.

It. is well known, that it has been the object of experiments, so far in vain, to construct a bullet that would be subject to no retarding influence on account of a vacuum, atthe rear surface thereof, or rather a vacuumless bullet.

The one main obstacle in this respect consisted in the difiiculty in discharging a bullet without simultaneously twisting, or bending or demolishing the tapered rear-portion of same; upon its travel through the gun-barrel, it being clearly understood, that such a bullet, as a main feature in solving this problem, inillst have a rearwardly tapered or pointed With these considerations in view and for the purpose of overcoming the said obstructions, I have devised a medium, in the form of a guide which may consist of any suit able material, such as, metal, compressed paper, fibre, wood, or the like substances, and which has for its object to encase the said bullet while in the shell and barrel of the gun, and protect and convey the said bullet over the critical point, that is through the barrel of the gun when the shot is fired. The further procedure is as follows: The bullet with its encasement, or guide, the latter hereinafter termed the caboose, leave the gun barrel together, but immediately the vacuum created by the flat or concave end of the caboose exerts a force suflicient to detach the caboose from the bullet thereby allowing the bullet to proceed unincumbered and without a vacuum, upon its course; the caboose itself falling to the ground. In this manner b the use of a caboose all of the well known enefits and advantagesof a vacuumless bullet are obtained without the loss of any of the propelling force of thefull powder charge.

With the above and other objects in view, this invention consists of the novel features of construction, combination and arrangements of parts, hereinafter fully described, claimed and illustrated in the accompanying drawings forming parts of this specification, and.in which similar characters of reference indicate corresponding parts in all views, and in which:

Figure 1 is substantially a longitudinal, transverse, sectional view, illustrating an embodiment of the main features of my device applied to a bullet; Fig. 2 is a similar View of the said device, while Figs. 3 and 4 are detail views specifically referring to the bullet itself.

Referring more particularly to the drawings 10 indicates a shell of the ordinary type; 11 des gnates the gunpowder, and 12 indicates the bullet with its tapered conical endportion 13. Constructed to snugly fit the said end-portion of the bullet is a caboose, or member 14, advancing at the front with its cylindrical sides to about the line 15, and having its rear portion constituting the inner end of the projectile. The said member 14 is of the same diameter as the bullet and fit, as formerly said, into the shell constituting the rear end of the said projectile.

The frontal portion of the member 14 is formed with a conical bore 16 terminating at the point 17 the depth and degree of tapering of the said member 14 corresponding exactly to the length and degree of tapering of the conical rear end of the bullet, 13.

. The said member 14 is provided with a diametrical aperture 18 at the point of the apex 17 in order tofacilitate the disengagement of the said member 14 from the bulletportion 13 after the aforesaid members, as a compact unit, have left the gun-barrel.

A groove 19 is formed in the outer surface of the member 14, and designed to contain greases, or oil. for the lubrication of the passage of the said member and bullet through the gun-barrel, as well as to collect carbon and other substances adhering to the interior of the gun-barrel.

The rear end 20 of the member 14 may be either fiat or provided with a concave surface; as indicated by dotted lines 21; while the distance between the said surface and the apex 17 of the cone may be varied according to the caliber of the bullet and its use.

In regard to the'bullet itself, I propose to make that with the tapered rear portion hollow, which act may be accomplished either Y b' constructing the said bullet, as shown in ig. 3, where the hard steel shell is only filled up with a concrete matter to about,.the,'line '22, or where its tapered end-portion com- ,as just described will prove ,a notable advam tage; thus sucha bullet will as formerly stated eliminate a vacuum space, and as the rear portion is hollow and of no weight, it will not in any manner interfere with the course of the bullet, as the latter with the said bullet-guide comprising a casing formed upon its frontal end surface with a central depression adapted to snugly fit the tapered rear portion of the said projectile, the said casing having a concrete rear end portion provided with a diametrically positioned tubular aperture intersecting the aforesaid fine point of therearwardly tapered sectionof the projectile for the purpose of affecting disengagement during operation, an annular recess dis posed upon the outersurface of the rear end of the said-guide, and a slight concave depression formed upon the end surface of the latter.

weight at its front will follow an unimpeded curve as destined.

From the foregoing it will be seen, that the said bullet with its vacuumless shape will be subject to the benefit of the full force of the powder charge, will be'protected and conveyed safely onits travel through the gunbarrel, and will after leaving the latter embark upon its course free and unimpeded,- gsgm'ng thereby potentialities of a magnitude that may prove revolutionary with respect to the science and technicgoverning this phase of industry. 7

It is obvious that changes may be made in the form, construction and arrangement of the several parts, as shown, within the scope of the appended claims, without departing from the spirit of the invention, and I do not therefore limit myself to the construction and arrangement shown and described herein.

What I claim as new, and desire to secure a by Letters Patent of the United States, is:

1. A combination offa projectile with a bullet-guide, the former comprising a substantially cylindrical middle section, a forwardly slanting slightly curved frontportion r and a rear portion tapered to a fine point, the

bullet-guide comprising a shell member pro-' vided at its front portion with a conical depression registering with the rear portion of the bullet, atransverse tubular perforation adapted to contact with the aforesaid fine point of the rear end of the bullet, an annular groove arranged upon the outer cylindrical surface of the said guide and near the end thereof and a concave depression formed upon the very end surface.

2. The combination of a proj bullet-guide, the said projectile comprising a front and a rear section the front section having a substantially cylindrical body with aforwardly diminishing slightly curved end portion, and the rear section consisting of a conical shell-portion tapered rearwardly to a fine point, and means for connecting said front and rear sections rigidly togethernhe ectile with a
